It is a kind of focal hydrocephalus caused by obstruction of flow pathway of cerebrospinal fluid. It is caused by various conditions, but ETH secondary to postoperative gamma-knife radiosurgery (GKS) is extremely rare. CASE SUMMARY A 52-year old previously healthy woman underwent resection of a large intraventricular meningioma. A small fragment of residual tumor with no obvious enlargement of the temporal horn was observed 3 mo after surgery, and she was referred for GKS. Two months after GKS, she complained of headache and progressive paralysis of the left limb. Magnetic resonance imaging revealed enlargement of the temporal horn. There was a second procedure to resect the residual tumor 8 mo after GKS. After the second procedure, she recovered smoothly. As of the date of this writing, she has remained in good condition. CONCLUSION This case reminds us that ETH should be considered in the treatment of intraventricular meningiomas, especially before GKS.展开更多

The mean follow-up time was 8.38 years. Patients’?age ranged between 16 and 78 years (mean 51). There were 35 patients who had been operated before, and two of them had been treated with fractionated radiotherapy. Twenty-three from 35 patients were surgically intervened?(65.7%)?and?presented post-surgical morbidity. Only in 3 cases the surgery was considered complete. The patients were referred for SRS treatment due to having tumour remains or a tumour growth. The mean volume of the tumour was 17.96 (+/?13.67) cm3.?All the patients had been treated with a Linear Accelerator (LINAC) using a high precision positioning and radiation system (SRS 2000) University of Florida. The clinical progress of the patients was assessed using preand post-SRS radiological imaging, post-surgical and pre-post-SRS morbidity and mortality. Tumour volume decreased significantly with RS in 61 of 82 patients (74.4%). The tumour volume remained stable 12 patients (14.6%) and only in 9 patients (11%) was there tumour growth after SRS. Of these, 5 required surgical intervention, and 7 of the 82 underwent SRS or another fractionated stereotactic radiotherapy after the RS. Morbidity due to the SRS was only seen in 14 out of the 82 patients treated with SRS, five of them recovered completely. SRS is a high precise and effective treatment with low morbidity, becoming more and more the option of choices?in the treatment of cavernous sinus meningioma.展开更多

However, the literature on the topic is still scarce. Aim: To test a novel AI commercially available tool for image analysis on a series of laparoscopic scenes. Methods: The research tools included OPENAI CHATGPT 4.0 with its corresponding image recognition plugin which was fed with a list of 100 laparoscopic selected snapshots from common surgical procedures. In order to score reliability of received responses from image-recognition bot, two corresponding scales were developed ranging from 0 - 5. The set of images was divided into two groups: unlabeled (Group A) and labeled (Group B), and according to the type of surgical procedure or image resolution. Results: AI was able to recognize correctly the context of surgical-related images in 97% of its reports. For the labeled surgical pictures, the image-processing bot scored 3.95/5 (79%), whilst for the unlabeled, it scored 2.905/5 (58.1%). Phases of the procedure were commented in detail, after all successful interpretations. With rates 4 - 5/5, the chatbot was able to talk in detail about the indications, contraindications, stages, instrumentation, complications and outcome rates of the operation discussed. Conclusion: Interaction between surgeon and chatbot appears to be an interesting frontend for further research by clinicians in parallel with evolution of its complex underlying infrastructure. In this early phase of using artificial intelligence for image recognition in surgery, no safe conclusions can be drawn by small cohorts with commercially available software. Further development of medically-oriented AI software and clinical world awareness are expected to bring fruitful information on the topic in the years to come.展开更多

文摘BACKGROUND Cauda equina syndrome(CES)is characterized by a group of symptoms that may be caused by inflammation,spinal cord compression,venous congestion,or ischemia.This syndrome is commonly an indication for surgical intervention but has not been determined as a postoperative complication following surgery for lumbar spine disease.CASE SUMMARY To report the case of a 54-year-old male patient who had CES following spinal surgery,with no obvious compression lesions found during re-exploration,suggesting that vascular insufficiency may have contributed to the condition.Furthermore,a series of urodynamic studies on bladder recovery patterns in such complications have also been investigated.CONCLUSION Postoperative CES requires urgent imaging and exploration to rule out compression;noncompressive cases,including vascular insufficiency may performed conservative management.
文摘BACKGROUND Odontogenic maxillary sinusitis,often triggered by dental issues like periapical periodontitis,significantly contributes to chronic sinusitis,mainly affecting adults around 50 years old,emphasizing the need for a multidisciplinary diagnostic and treatment approach.AIM To investigate the therapeutic effect and clinical value of root canal therapy combined with nasal endoscopic surgery compared with simple root canal the-rapy in the treatment of severe odontogenic maxillary sinusitis caused by peria-pical periodontitis.METHODS The clinical data,diagnosis,and treatment of 200 patients with severe odonto-genic maxillary sinusitis caused by periapical periodontitis from October 2020 to October 2021 were analyzed retrospectively.Among them,63 patients were treated with simple root canal therapy as the control group,and 137 patients were treated with root canal therapy combined with nasal endoscopic surgery as the observation group.The therapeutic effect,Lund-Kennedy endoscopic score,paranasal sinus Lund-Mackay score,complication rate,recurrence rate,and patient satisfaction were compared between the two groups.RESULTS First,we compared the effective rates:23 cases were cured,22 were improved,and 8 were ineffective in the control group,yielding a total effective rate of 84.90%.Meanwhile,97 cases were cured,34 improved,and 6 were ineffective in the observation group,resulting in a total effective rate of 95.62%.The observation group had a higher total effective rate compared with the control group(P<0.05).Second,we compared the Lund–Kennedy endoscopic score.Before treatment,no significant difference(P>0.05)was observed in this score between the two groups.After treatment,the Lund–Kennedy endoscopic score decreased in both groups.The Lund–Kennedy endoscopic score of the observation group at 3 and 6 mo after treatment was lower compared to that of the control group(P<0.05).Third,we compared the Lund–Mackay score of paranasal sinuses.Before treatment,there was no significant difference in this score between the two groups(P>0.05).After treatment,the Lund–Mackay scores of paranasal sinuses decreased in both groups.The Lund–Mackay scores of paranasal sinuses in the observation group at 3 and 6 mo after treatment were lower compared to those of the control group(P<0.05).Fourth,we compared the incidence and recurrence rate of complications.Three months after treatment,no significant difference was found in the incidence and recurrence rate of complications between the observation group(6.56%)and the control group(9.52%)(P>0.05).However,6 mo after treatment,the incidence and recurrence rate of complications in the observation group(2.91%)was significantly higher compared to that of the control group(12.69%)(P<0.05).Fifth,we compared patient satisfaction.Six months after treatment,the patient satisfaction of the observation group(93.43%)was significantly better than that of the control group(84.12%)(P<0.05).CONCLUSION Root canal therapy combined with nasal endoscopic surgery has a good therapeutic effect on severe odontogenic maxillary sinusitis caused by periapical periodontitis,and it can reduce the injury of maxillary sinus mucosa and bone,and significantly reduce the incidence of complications and recurrence rate.Meanwhile,it has high patient satisfaction and remarkable therapeutic effect,which is suggested to be popularized and applied in clinic.
文摘Pulmonary embolism(PE)is a rare but devastating complication of shoulder surgery.Apart from increased morbidity and mortality rates,it may significantly impair postoperative recovery and functional outcome.Its frequency accounts for up to 5.7%of all shoulder surgery procedures with a higher occurrence in women and patients older than 70 years.It is most commonly associated with thrombophilia,diabetes mellitus,obesity,smoking,hypertension,and a history of malignancy.PE usually occurs secondary to upper or lower-extremity deep vein thrombosis(DVT).However,in rare cases,the source of the thrombi cannot be determined.Prophylaxis for PE following shoulder surgery remains a topic of debate,and the standard of care does not routinely require prophylactic medication for DVT prophylaxis.Early ambulation and elastic stockings are important preventative measures for DVT of the lower extremity and medical agents such as aspirin,low-molecular-weight heparin,and vitamin K antagonists are indicated for high-risk patients,long-lasting operations,or concomitant severe acute respiratory syndrome coronavirus 2 infection.The most common symptoms of PE include chest pain and shortness of breath,but PE can also be asymptomatic in patients with intrinsic tolerance of hypoxia.Patients with DVT may also present with swelling and pain of the respective extremity.The treatment of PE includes inpatient or outpatient anticoagulant therapy if the patient is hemodynamically unstable or stable,respectively.Hemodynamic instability may require transfer to the intensive care unit,and cardiovascular arrest can be implicated in fatal events.An important issue for patients with PE in the postoperative period after shoulder surgery is residual stiffness due to a delay in rehabilitation and a prolonged hospital stay.Early physiotherapy and range-of-motion exercises do not adversely affect the prognosis of PE and are highly recommended to preserve shoulder mobility and function.
文摘Restoring the balance of gut microbiota has emerged as a critical strategy in treating intestinal disorders,with probiotics playing a pivotal role in maintaining bacterial equilibrium.Surgical preparations,trauma,and digestive tract reconstruction associated with intestinal surgeries often disrupt the intestinal flora,prompting interest in the potential role of probiotics in postoperative recovery.Lan et al conducted a prospective randomized study on 60 patients with acute appendicitis,revealing that postoperative administration of Bacillus licheniformis capsules facilitated early resolution of inflammation and restoration of gastrointestinal motility,offering a novel therapeutic avenue for accelerated postoperative recovery.This editorial delves into the effects of perioperative probiotic supplementation on physical and intestinal recovery following surgery.Within the framework of enhanced recovery after surgery,the exploration of new probiotic supplementation strategies to mitigate surgical complications and reshape gut microbiota is particularly intriguing.
文摘Anastomotic leakage(AL)is a significant complication following rectal cancer surgery,adversely affecting both quality of life and oncological outcomes.Recent advancements in artificial intelligence(AI),particularly machine learning and deep learning,offer promising avenues for predicting and preventing AL.These technologies can analyze extensive clinical datasets to identify preoperative and perioperative risk factors such as malnutrition,body composition,and radiological features.AI-based models have demonstrated superior predictive power compared to traditional statistical methods,potentially guiding clinical decisionmaking and improving patient outcomes.Additionally,AI can provide surgeons with intraoperative feedback on blood supply and anatomical dissection planes,minimizing the risk of intraoperative complications and reducing the likelihood of AL development.
文摘BACKGROUND Unilateral biportal endoscopic(UBE)surgery has developed rapidly during the past decade.Continuous epidural space irrigation is generally considered the principal reason for cerebral complications following UBE surgery.We present a case of mental symptoms during the general anesthesia awakening period due to pneumocephalus.CASE SUMMARY A 70-year-old woman with lumbar disc herniation underwent UBE surgery stably under general anesthesia.Uncontrollable hypertension occurred immediately after transfer to the postoperative care unit,accompanied by increased heart rate and tachypnea.During the recovery process,the patient responded to external stimuli but was confused and unable to complete command actions.Neck stiff-ness and significantly increased muscle strength on the left side indicated the presence of de-cerebrate rigidity.An urgent brain computed tomography scan showed pneumocephalus compressing the brainstem.After receiving analgesia and sedation treatment,the patient was conscious three hours later and recovered rapidly.She was discharged on the fifth postoperative day and followed up for 3 months with no surgical or brain complications.CONCLUSION Cerebral complications emerging during the general anesthesia awakening period following UBE surgery are not entirely due to increased intracranial pressure.Pneumocephalus induced by dural injury may also be a potential cause.

文摘BACKGROUND Laparoscopic cholecystectomy(LC)and laparoscopic common bile duct exploration(LCBDE)are widely used in gallbladder and biliary tract diseases.During these procedures,vessels or tissues are commonly ligated using clips.However,postoperative migration of clips to the common bile duct(CBD)or Ttube sinus tract is an overlooked complication of laparoscopic biliary surgery.Previously,most reported cases of postoperative clip migration involved metal clips,with only a few cases involving Hem-o-lok clips and review of the literature.CASE SUMMARY This report describes two cases in which Hem-o-lok clips migrated into the CBD and the T-tube sinus tract following laparoscopic surgery.Case 1 is a 68-year-old female admitted due to abdominal discomfort,and two Hem-o-lok clips were found to have migrated into the CBD 17 months after LC and LCBDE with T-tube drainage,and were removed using a stone extraction balloon.The patient was discharged smoothly after recovery.Case 2 is a 74-year-old male who underwent LC and LCBDE with T-tube drainage and laparoscopic biliary tract basket stone extraction.Nine weeks postoperatively,following T-tube removal,a Hem-o-lok clip was found in the sinus tract,and was extracted from the T-tube sinus tract.The patient recovered smoothly postoperatively.This study also reviews the literature from 2013 to July 2024 on using Hem-o-lok clips in LC and/or LCBDE treatment of gallbladder and biliary diseases and the postoperative migration of these clips into the CBD,T-tube sinus tract,or duodenum.CONCLUSION In patients with a history of LC and/or LCBDE,clip migration should be considered as a differential diagnosis.
文摘BACKGROUND Entrapment of the temporal horn (ETH) is a rare pathologic condition. It is a kind of focal hydrocephalus caused by obstruction of flow pathway of cerebrospinal fluid. It is caused by various conditions, but ETH secondary to postoperative gamma-knife radiosurgery (GKS) is extremely rare. CASE SUMMARY A 52-year old previously healthy woman underwent resection of a large intraventricular meningioma. A small fragment of residual tumor with no obvious enlargement of the temporal horn was observed 3 mo after surgery, and she was referred for GKS. Two months after GKS, she complained of headache and progressive paralysis of the left limb. Magnetic resonance imaging revealed enlargement of the temporal horn. There was a second procedure to resect the residual tumor 8 mo after GKS. After the second procedure, she recovered smoothly. As of the date of this writing, she has remained in good condition. CONCLUSION This case reminds us that ETH should be considered in the treatment of intraventricular meningiomas, especially before GKS.

文摘The top goal of modern medicine is treating disease without destroying organ structures and making patients as healthy as they were before their sickness.Minimally invasive surgery(MIS)has dominated the surgical realm because of its lesser invasiveness.However,changes in anatomical structures of the body and reconstruction of internal organs or different organs are common after traditional surgery or MIS,decreasing the quality of life of patients post-operation.Thus,I propose a new treatment mode,super MIS(SMIS),which is defined as“curing a disease or lesion which used to be treated by MIS while preserving the integrity of the organs”.In this study,I describe the origin,definition,operative channels,advantages,and future perspectives of SMIS.
文摘Diabetes mellitus(DM)and obesity have become public issues of global concern.Bariatric surgery for the treatment of obesity combined with type 2 DM has been shown to be a safe and effective approach;however,there are limited studies that have systematically addressed the challenges of surgical treatment of obesity combined with DM.In this review,we summarize and answer the most pressing questions in the field of surgical treatment of obesity-associated DM.I believe that our insights will be of great help to clinicians in their daily practice.
文摘The cases of 82 patients with cavernous sinus meningioma (CSM) treated with Stereotactic Radiosurgery (SRS) at our institution from 1992 to 2005 were retrospectively reviewed. The mean follow-up time was 8.38 years. Patients’?age ranged between 16 and 78 years (mean 51). There were 35 patients who had been operated before, and two of them had been treated with fractionated radiotherapy. Twenty-three from 35 patients were surgically intervened?(65.7%)?and?presented post-surgical morbidity. Only in 3 cases the surgery was considered complete. The patients were referred for SRS treatment due to having tumour remains or a tumour growth. The mean volume of the tumour was 17.96 (+/?13.67) cm3.?All the patients had been treated with a Linear Accelerator (LINAC) using a high precision positioning and radiation system (SRS 2000) University of Florida. The clinical progress of the patients was assessed using preand post-SRS radiological imaging, post-surgical and pre-post-SRS morbidity and mortality. Tumour volume decreased significantly with RS in 61 of 82 patients (74.4%). The tumour volume remained stable 12 patients (14.6%) and only in 9 patients (11%) was there tumour growth after SRS. Of these, 5 required surgical intervention, and 7 of the 82 underwent SRS or another fractionated stereotactic radiotherapy after the RS. Morbidity due to the SRS was only seen in 14 out of the 82 patients treated with SRS, five of them recovered completely. SRS is a high precise and effective treatment with low morbidity, becoming more and more the option of choices?in the treatment of cavernous sinus meningioma.

文摘BACKGROUND This study was designed to investigate the clinical outcomes of enhanced recovery after surgery(ERAS)in the perioperative period in elderly patients with nonsmall cell lung cancer(NSCLC).AIM To investigate the potential enhancement of video-assisted thoracic surgery(VATS)in postoperative recovery in elderly patients with NSCLC.METHODS We retrospectively analysed the clinical data of 85 elderly NSCLC patients who underwent ERAS(the ERAS group)and 327 elderly NSCLC patients who received routine care(the control group)after VATS at the Department of Thoracic Surgery of Peking University Shenzhen Hospital between May 2015 and April 2017.After propensity score matching of baseline data,we analysed the postoperative stay,total hospital expenses,postoperative 48-h pain score,and postoperative complication rate for the 2 groups of patients who underwent lobectomy or sublobar resection.RESULTS After propensity score matching,ERAS significantly reduced the postoperative hospital stay(6.96±4.16 vs 8.48±4.18 d,P=0.001)and total hospital expenses(48875.27±18437.5 vs 55497.64±21168.63 CNY,P=0.014)and improved the satisfaction score(79.8±7.55 vs 77.35±7.72,P=0.029)relative to those for routine care.No significant between-group difference was observed in postoperative 48-h pain score(4.68±1.69 vs 5.28±2.1,P=0.090)or postoperative complication rate(21.2%vs 27.1%,P=0.371).Subgroup analysis showed that ERAS significantly reduced the postoperative hospital stay and total hospital expenses and increased the satisfaction score of patients who underwent lobectomy but not of patients who underwent sublobar resection.CONCLUSION ERAS effectively reduced the postoperative hospital stay and total hospital expenses and improved the satisfaction score in the perioperative period for elderly NSCLC patients who underwent lobectomy but not for patients who underwent sublobar resection.
文摘Objective:The aim of our study was to find out the best operative therapeutic regimen by reviewing the comprehension of operation,the improvement of operative method and the selection of operative approach concerning pineal region meningioma combining obstructive hydrocephalus.Methods:We retrospected the clinic data,comprehension of operation and prognosis of 6 cases of pineal region meningioma.Results:Six tumors were all removed,after that the back wall of the third ventricle was cut open.The 6 tumors were defined as meningioma by pathological examination.After 4-48 months follow-up,the manifestation of hydrocephalus disappeared,other symptoms were relieved more or less without any complication with one patient dismissing.The regular MRI examination indicated that the lesions had not reoccur and the cerebral ventricles had been normal.Conclusion:We identify the nourish arteries of the tumor and anatomy relationship between the tumor and its peripheral blood vessels through modern imaging devices,to select reasonable operative method are the premier therapy of pineal region meningioma.The back wall of the third ventricle becomes thin and the suprapineal recess develops shallow and wide,so the third ventricle-quadrigeminal cistern fistulation can effectively eliminate the obstructive hydrocephalus due to the long-term compression on the aqueduct after removing the tumor.
文摘Introduction: Ultrafast latest developments in artificial intelligence (ΑΙ) have recently multiplied concerns regarding the future of robotic autonomy in surgery. However, the literature on the topic is still scarce. Aim: To test a novel AI commercially available tool for image analysis on a series of laparoscopic scenes. Methods: The research tools included OPENAI CHATGPT 4.0 with its corresponding image recognition plugin which was fed with a list of 100 laparoscopic selected snapshots from common surgical procedures. In order to score reliability of received responses from image-recognition bot, two corresponding scales were developed ranging from 0 - 5. The set of images was divided into two groups: unlabeled (Group A) and labeled (Group B), and according to the type of surgical procedure or image resolution. Results: AI was able to recognize correctly the context of surgical-related images in 97% of its reports. For the labeled surgical pictures, the image-processing bot scored 3.95/5 (79%), whilst for the unlabeled, it scored 2.905/5 (58.1%). Phases of the procedure were commented in detail, after all successful interpretations. With rates 4 - 5/5, the chatbot was able to talk in detail about the indications, contraindications, stages, instrumentation, complications and outcome rates of the operation discussed. Conclusion: Interaction between surgeon and chatbot appears to be an interesting frontend for further research by clinicians in parallel with evolution of its complex underlying infrastructure. In this early phase of using artificial intelligence for image recognition in surgery, no safe conclusions can be drawn by small cohorts with commercially available software. Further development of medically-oriented AI software and clinical world awareness are expected to bring fruitful information on the topic in the years to come.

文摘Accurate segmentation of oral surgery-related tissues from cone beam computed tomography(CBCT)images can significantly accelerate treatment planning and improve surgical accuracy.In this paper,we propose a fully automated tissue segmentation system for dental implant surgery.Specifically,we propose an image preprocessing method based on data distribution histograms,which can adaptively process CBCT images with different parameters.Based on this,we use the bone segmentation network to obtain the segmentation results of alveolar bone,teeth,and maxillary sinus.We use the tooth and mandibular regions as the ROI regions of tooth segmentation and mandibular nerve tube segmentation to achieve the corresponding tasks.The tooth segmentation results can obtain the order information of the dentition.The corresponding experimental results show that our method can achieve higher segmentation accuracy and efficiency compared to existing methods.Its average Dice scores on the tooth,alveolar bone,maxillary sinus,and mandibular canal segmentation tasks were 96.5%,95.4%,93.6%,and 94.8%,respectively.These results demonstrate that it can accelerate the development of digital dentistry.
文摘BACKGROUND We report a case of uterine artery pseudoaneurysm(UAP)occurrence during hysteroscopic endometrial polypectomy and its treatment via uterine artery embolization(UAE).CASE SUMMARY A 48-year-old primigravid,primiparous patient was incidentally found to have an endometrial polyp during a health checkup,and underwent a hysteroscopic polypectomy at another hospital.Her cervix was dilated with a Laminken-R®device.After the Laminken-R®was withdrawn,a large amount of genital bleeding was observed.This bleeding persisted after the hysteroscopic polypectomy,and,as hemostasis became impossible,the patient was transferred to our hospital by ambulance.On arrival,transvaginal ultrasonography revealed a 3-cm hypoechoic mass with a swirling internal pulse on the right side of the uterus,and color Doppler ultrasonography showed feeder vessels penetrating the mass.Pelvic contrast-enhanced computed tomography(CT)confirmed the presence of a mass at this site,and vascular proliferation was observed within the uterine cavity.Consequently,UAP was diagnosed,and UAE was performed.The patient’s postoperative course was uneventful,and 6 mo post-UAE,no recurrence of blood flow to the UAP was observed.CONCLUSION When abnormal genital bleeding occurs during hysteroscopic surgery,ultrasonography and contrast-enhanced CT can assist in the detection of early UAPs.
